This application is a division of application Serial No. 703,176 filedDecember 20, 1933, which issued as Patent No. 2,006,795 on July 2, 1935.

This invention relates to a summary board whereby a plurality of sheetsmay be suspended in horizontal overlapping relationship so that singlecolumns on each of the suspended sheets may be held in juxtaposedpositions to facilitate summarization of the data contained in theexposed columns. The invention relates particularly to means foraligning a line guide with reference to the sheets. It is an object ofthis invention to provide means for quickly and accurately adjusting theangularity of the line guide, without any need of tools, to insureaccurate alignment of the reading edge of the line guide with respect tothe sheets suspended in horizontal overlapping relationship. Otherobjects of this invention will become apparent upon reading thefollowing description taken in conjunction with the accompanyingdrawings in which:

Figure 1 is a perspective View of my summary board;

Figure 2 is a fragmentary perspective view illustrating the housingcarrying the line guide; 1 Figure 3 is a top plan View of the housingwith parts broken away to facilitate illustration of the structuraldetails; Figure 4 is a cross sectional view taken along the line IV-IVof Figure 3 looking in the direction of the arrows; and

Figure 5 is a cross sectional view taken along the line V-V of Figure 3looking in the direction of the arrows. In the drawings, the referencenumeral 2 indicates a flat plate member adapted to be supported at anydesired angle by means of an easel structure 3. The preferred easelstructure does not constitute part of this invention and is fullydescribed in United States Letters Patent No. 1,883,255 issued October18, 1932, to Paul O. Unger. The fiat plate structure will not bedescribed in detail because it is fully described in United StatesLetters Patent No. 2,000,558, issued May 7, 1935, to applicant and PaulO. Unger.

The flat plate member 2 is provided with a channel shaped depressedportion 4 adjacent its upper edge. This channel shaped depressed portion4. is providedwith a fixed lug 5 at one end and a slidable lug 6 at theother end and is adapted to receive a ring bar 1 of any suitable design.The ring bar "I is provided with open ends into which the lugs 5 and 6are adapted to fit to secure board, it is not sufficient merely to havethe sheets aligned properly, but it is also necessary to have the lineguide parallel with the line of figures being summarized. My line guidemechanism includes a line guide 9 rigidly secured to a housing I adaptedto travel up and down a rod II spaced from one end of the flat platemember 2 T and secured in place by a pair of flat strips I2, I3(Figure 1) extending from one end of the plate member 2 adjacent the topand bottom. The rod I I is secured to the strips I2, I3 by means ofscrews or rivets. A portion of the peripheral surface of the rod II isserrated, as indicated at I4, Figures 3, 4 and 5. A metal plate I5,U-shaped in cross section, is mounted in the housing I0 on one side ofthe rod II. A pair of rollers I 6, I1 is mounted in the plate I by meansof the studs I8, I9, The periphery of the roller I! is serrated, asindicated at 29, to enable the roller IT to mesh with the serrations I4.A pair of coiled springs 2|, 22 mounted between the plate I5 and thehousing I0 exert a constant force against the plate I 5 to maintain theroller I! in positive engagement with the serrations I4. The springs 2I,22 are positioned by 25 means of the studs 23, 24. One end of the studI9 is extended beyond the front wall of the housing II! and carries aknob 25 which may be rotated to move the housing along the rod II Theaperture in the housing through which the stud I9 passes is slightlyelongated, as indicated at 26, Figure 2, for a purpose to be hereinafterdescribed.

A roller 21 is mounted in the housing I 0 on the opposite side of therod I I by means of a stud 28. A metal plate 29, U-shaped in crosssection, is mounted in the housing I 0 on the opposite side of the rodII from the plate I5 by means of a stud 30. The stud 39 is spacedcentrally of the plate 29 so that the'plate 29 may be pivotally 40 movedaround the stud 30 as a center. Another roller 3I is mounted in theplate 29 adjacent its upper edge by means of a stud 32. A threaded stud33 is rigidly secured to the plate 29 adjacent its'lower edge andextends through one wall of the housing I U. A threaded adjusting nut 34is mounted on the portion of the threaded stud 33 outside of the housingI0. The angularity of the line guide 9 is adjusted simply by rotatingthe nut 34. If the free end of the line guide is lower than the endsecured to the housing, the nut 34 is rotated so as to move the loweredge of the plate 29 to the left (Figure 3). Since the rod II is fixed,the roller 3I cannot move to the right, and since the housing and plate29 are secured together by the stud 30, the plate 29 acts as a lever ofthe second class and pulls the upper edge of the housing to the left.The lower edge of the housing cannot move any substantial distance tothe left because the slot 26 (Figure 2) is elongated only very slightly,and the right end of the slot 26 soon contacts with the stud I9. In viewof the fact that the roller 21 is fixed to the housing and cannot moveto the right because it is in contact with the rod II which is alsofixed, the roller 2'! acts aspivot point for the housing. The portion ofthe slot 26 extending to the left of the stud I9 permits the slightmovement of the housing with respect to the stud l9 necessary to permitthe counterclockwise pivotal movement of the housing around the roller21 as pivot. The rigid securement of the line guide to the housingcauses the line guide to move angularly with the housing. It will beunderstood that the apertures in the housing through which the rod I Ipasses are sufficiently large to allow the slight movement of thehousing necessary to adjust the anglr arity of the line guide.

The angular movement of the housing and line guide above mentionedcompresses the spring 2|. When the nut 34 is moved in the oppositedirection from that described above, the spring 2| expands and moves theupper edge of the housing to the right (Figure 3). The lower edge of thehousing is prevented from moving to the right by the roller 2'! which isfixed to the housing and is in contact with the rod ll. Accordingly, thehousing is pivotally moved in clockwise direction and the free end ofthe line guide is moved downwardly. Obviously, the degree of angularmovement of the line guide in either direction can be controlledaccurately by means of the threaded adjusting nut.

While I have described my invention with particular reference to its usein connection with a summary board, it will be obvious that the devicemay be used with any copyhc-lder or reading device where the angularityof the line guide is important. It will also be understood that thedescription of my device is illustrative, rather than restrictive, asmany details may be modified or changed without departing from thespirit or scope of my invention. Accordingly, I do not desire to berestricted to the exact construction described, except as limited by theappended claims.
